Add Effects, Change Pitch & Speed Of Songs

Last month, we covered BPMinus, an application for Windows that allows you to play and control the speed of music tracks while maintaining their pitch, as well as the sound quality. Even though BPMinus performed excellent in our testing, there was still some change in pitch while manipulating the track speed (the app advertised being able to change all parameters in isolation). Today, we have an open source application called Audio Pitch & Shift, made for the same purpose of changing the pitch and playback speed of songs, but it performs the required function better than a lot of the software currently in the market. When you are changing the speed or pitch of the song, it doesn’t affect the other parameters at all. Other than speed and pitch, Audio Pitch & Shift also allows you to introduce and include different effects in the music track, such as Distortion, Chorus, Ranger, Echo, Reverb etc. It supports a large number of file extensions for pitch and speed manipulation, including MP3, OGG, WMA, WAV, MPEG, FLAC, AAC etc. More on Audio Shift & Pitch after the break.

All the controls required to change the pitch or speed of the audio track can be accessed directly from the main interface. The Playback Controls are available at the top, the Volume, Mixer and Effects controls are in the center, while the Settings for applying different effects on to the songs, including Distortion, Chorus, Ranger, Echo, Reverb, Priority and Modules, can be accessed from the right side of the main interface. Each control has sliders to easily increase or decrease the intensity of the selected effect.

The Track list button, available on the right side of the playback controls, allows you to add multiple songs in the playlist, letting you use the application as a normal media player as well.


The program’s features, according to the product page, are as follows.

  • Change speed of music without affecting pitch
  • Change pitch (in semitones) of music without affecting speed
  • BPM Detection
  • Distortion, Chorus, Flanger, Echo and Reverb FX (DirectX 8 required)
  • Loop mode
  • Render file with selected speed, pitch and FX in MP3, WMA, WAV format

Audio Pitch & Shift is a portable application that works on both 32-bit and 64-bit versions of Windows XP, Windows Vista, Windows 7 and Windows 8.
